29% waxing, crescent Moon

A tripod mounted Panasonic Lumix DMC-FZ72 bridge camera at 60x optical zoom was used to image the 29% waxing, crescent Moon. The camera was set to ISO-100 and 1/100s exposure at f/5.9. 60 images, were precisely cropped and registered in Nicola Mackin's AstroCrop software and then stacked and wavelet processed in Registax 5.

Whole disk H-alpha imaging

Whole disk H-alpha imaging imaging with a Solarmax ll 60 Bf15 H-alpha scope and an Opticstar PL-130M monochrome CMOS camera. Two AVIs were captured. One exposed for the disk and the second exposed for the prominences. The two resulting images were combined in Photoshop. Click on the image to get a closer view:

The Sun in H-alpha and Ca K-line light

A DMK camera was used with a Solarmax ll 60 BF15 H-alpha scope and a CaK PST Ca K-line scope to image the Sun. In each case, AVIs were captured in 4 overlapping quadrants of the solar disk. The AVIs were stacked in Registax 5 and the resulting images merged in Photoshop. A region with two large prominences was imaged twice, once exposed for the disk and a second time exposed for the prominences. The two images were combined in Photoshop.

Whole disk H-alpha solar imaging

An Opticstar PL-130M CMOS camera was used with a Solarmax ll 60 BF15 H-alpha scope to capture a 1000 frame AVI of the whole solar disk. The AVI was stacked in Registax 5 to produce the final image. Click on the image to get a closer view:

6% waxing, crescent Moon

A tripod mounted Panasonic Lumix DMC-FZ72 bridge camera at 60x optical zoom was used to image the 6% waxing, crescent Moon. The camera was set to ISO-400 and 1/80s exposure at f/5.9. 36 images, were precisely cropped and registered in Nicola Mackin's AstroCrop software and then stacked and wavelet processed in Registax 5.

Solar activity in H-alpha light

Active areas of the Sun were imaged with a Solarmax ll BF15 H-alpha scope. A DMK camera fitted with the lens of a x2 Barlow. 2500 frame AVIs were captured and processed in Registax 5. The resulting images were merged in Photoshop. Click on the image to get a closer view:

The Sun in white light with a bridge camera

A static tripod mounted Panasonic Lumix DMC-FZ72 bridge camera at 60x optical zoom, fitted with a Baader solar filter, was used to image the Sun. The camera was set to burst mode, ISO-100 and 1/1000s exposure at f/5.9. Images were captured in bursts of three. 60 images, precisely cropped and registered in Nicola Mackin's AstroCrop software were stacked and wavelet processed in Registax 5.
